EXTENSION-HOOK.

Specification of Letters Patent.

Patented Feb. 22, 1910.

Application filed May 18, 1909. Serial No. 496,745.

'0 all whom it may concern:

Be it known that I, JOSEPH M. ZUK, a citizen of Russia, residing at NewBritain, in the county of Hartford and State of Connecticut, haveinvented certain new and useful Improvements in Extension-Hooks, ofwhich the following is a specification.

My invention relates to improvements in extension hooks for lacecurtains and shade rollers, and the objects of my improvements aresimplicity and economy in construction and convenience and etficiency inuse.

In the accompanying drawings :-Figure 1 is a perspective View of theupper part of a Window casing with a pair of my extension hooks inposition. Fig. 2 is a perspective view of one of my extension hooks, onan enlarged scale. Fig. 3 is an end view of the same. Fig. 4 is a rearview of the same in part broken out. Fig. 5 is a side elevation of thebracket to my extension hook, previous to bending.

A is the bracket to my extension hook, formed of sheet metal, providedwith a laterally extending supporting arm 10, and a hook shaped arm 11,which in the finished article extends forwardly from the said laterallyextending supporting arm 10. The said supporting arm has parallel topand bottom edges and in the top edge is provided with a series oftransverse locking slots 12. As shown the said hook shaped arm 11 inprojecting forward drops downward and then swings upward by a sweepingcurve, and at about the low point of the curve is provided with a shaderoller receiving slot 13 in the upper edge, which is at a suitabledistance forward to have a shade roller B and shade supported in thesaid slot clear the window casing C. At the forward end the said hookshaped arm 11 is provided with an upwardly projecting and integral pin14, adapted to be received in a suitable hole in a lace cnrtainpole Dfor supporting the same. E is the bracket support for my extension hook,made of sheet metal and comprises essentially a shallow box like body16, provided with narrow vertical slots 17 in the two opposed verticalside walls 18 adapted to fittingly receive and support the said lateralsupporting arm 10 of the bracket A. The said bracket support E may beprovided as shown with support ing ears 19, extending upward anddownward respectively from the top and bottom walls 20 of the said boxlike body 16, the

said lugs having holes 21 suitable for supporting screws. One of theside walls 18 is provided with a locking latch l pivoted at the upperend on the pin 22 so that the lower edge 23 swings across the space ofthe slots 17 when swinging downward and of a thick ness such as to bereceivable in any of the said series of locking slots 12 in the said topedge of the supporting arm 10 of the bracket A, and provided with aforwardly projecting tip or handle 21, which projects suitably in frontof the front face 25 of the said body 16 for convenience in operating.

As set up for use the said bracket support E is first secured to thewindow casing C by screws in the screw holes 21 so that when the saidsupporting arm 10 is in position in the slots 17 the bracket A. may heslid horizontally back and forth. Then the bracket A is placed inposition for support by means of the arm 10 in the slots 17 asdescribed. A pair of brackets A would include one right handed and oneleft handed as shown in Fig. 1. By sliding the brackets laterally theymay be adjusted for spread to accommodate different lengths of poles androllers, different width of windows, and differences in the spread ofthe bracket supports, and when finally adjusted they may be locked inadjustment by means of the locking latch and locking slots as described.

For convenience in production and shipment, I prefer to make up thebrackets to my extension hook flat, as shown in Fig. By this plan theymay be packed to take up a minimum of space, and no attention from aproduction standpoint need be given to the feature of mating up rightsand lofts. I accomplish this result by making the bracket of bendablematerial, so that the same may be bent across the supporting arm 10, asat the dotted line 26 shown in the said Fig. 5, to make either a rightor a left as desired.

Special attention may be given to the design and finish of the parts toobtain a pleasing effect, so that while performing the useful functionof a combination support for lace curtains and a curtain shade my devicemay in itself be ornamental as well.

I claim as my invention:

In an extension hook for curtains in combination a bracket, a bracketholder, and a latch, the said bracket comprising a forwardly extendingmember adapted for a curtain support, and a laterally extending the saidlatch above the corresponding slot 10 in said side Wall, the said latchcomprising a flat plate pivotally mounted by said means, adapted to beoperated so as to engage with said kerfs.
